SPECIFICATION forming part of Letters Patent No. 336,711, dated February 23, 1886.

Application filed November ll, 1885. Serial No. 183,567. (No model.)

To all whom it may concern:

Be it known that we, Trronms A. GAL'I and GEORGE S. TRACY, citizens of the United States, residing at Sterling, in the county of Whiteside and State of Illinois, have invented reference marked thereon, which orm a part of this specification.

Our invention pertains to disk-seeders, and has more special reference to improvements thereof in the following particulars: first, means for forcing the scrapers into contact with the disks; second, means for avoiding the oscillation of the gangs in a vertical plane and for rendering such gangs rigid in such plane; third, means for automatically adapting the chain which drives the seeding devices to the variant position of the disk-gangs.

In the drawings, Figure 1 is a rear elevation of the portion of the machine embodying the first branch of our invention. Fig. 2 is a detail plan of means for preventing vertical oscillation of the disk-gangs. Fig. Sisadetail plan of the lever for tightening the sprocket-chain. Fig. 4 is an end elevation of the mechanism for driving the seeder-shaft. Fig. 5 is a rear view of the mechanism for regulating the scrapers.

Referring to the first branch, A is the usual transverse beam,to which th e'usual disk-gangs, B, are attached in any of the ordinary modes. 0 is a scraper-bar attached to the beam A, parallel thereto by being seated loosely in the clips D, fastened to the beam A. E E are scraper-arms, which at their upper ends loosely encircle the bar 0, and are held in place by means of set-screws a, and are thus readily adjusted on the bar 0, or removed and replaced in case of breakage, or if it be desired to substitute other species of scrapers.

F F are the scrapers. A foot'lever, l, is journaled horizontally on and across the beam 13, and has its forward end bent in convenient shape to be actuated by the foot of the driver. A clip, b, having a rearward horizontal projection, b, is placed rigidly around the bar 0, and the rear end of the lever G is bent downward and. inserted loosely in a hole formed vertically through the projection b. It is undesirable to have the scrapers in continuous contact with the disks, as thereby mud and rubbish become wedged between the parts. In our construction the driver, by means of the lever (.i, can drive the scrapers to or from the disks, as desired, without interfering with his management of the team, and if the rear end of such lever be weighted it will automatically withdraw such scrapers from the disks, thus reducing the labor of the driver in this behalf onehnlf.

In reference to the second branch of our improvements, Fig. 2, -it is sometimes desirable on rough ground to have the implement level the ground, and, instead of adjusting itself to inequalities, to cut deeper into the ridges and fill up depressions therefrom. In order to accomplish this and render the gangs rigid as to oscillation in a vertical plane, to the lower side of the tongue II, and in the interval. between the adjacent ends of the disk-gain gs, we bolt the plate .I, by means of vertical bolts (Z (I, passed through the tongue and such plate. The plate J extends laterally a short distance from the tongue ll on each side thereof. A short plate, K, is bolted to the upper side of the inner ends, respectively, of the beams B, and projects inwardly and beyond the inner end of such beam sul'liciently to rest upon the upper surface of the plate J. Ilhelatter plate is long cnonglnto permit some horizontal oscillation of the gangs without disengaging the plates J and K. r\ is the draft-beam, to which the disk-beams lidll'O attached near their outer ends in any of theusual modes, and extends across the adjacent ends of the beams 15. Blocks 0 e are respeeli vel y fastened to the lower side of the beam A. at such point as to nearly or quite touch the upper surface of the diskbeams B near the inner ends of the latter, respectively. The plates K and J prevent the end of the dislebeam from moving downward, and the block 0 prevents such end from rising, and both gangs of disks are thereby held in a position substantially parallel with the draftbeam A. \Vhen it is desired to allow the disk gangs their usual vertical oscillations, the plate K, by means of the slot K therein, can be moved outward, so as not to engage the plate J.

In reference tolthe fourth branch of our ing vention, M is the seed-hopper; imposed on the forward portion o'f the draft-plahk' A, and provided with the usual seed-,holes in its bottom. N is a sprocket-wheel, placed outside of the hopper M on the usual stirring-shaft, N, which passes through such hopper and is provided with the usual wings for keeping such seedholes clear of rubbish and the seed in agitation. V is the drivingsprocket wheel, rigidly attached to the outer end of the axle W of one of the disk-gangs. P is a stationary pulley, seated on the rear portion of the beam A, and in line with the wheel N. O is asprocket-chain passed around the wheelsN and NV and the pulley P, and intended to rotate the stirringshaft N. R is alever pivoted at its front end in any suitable way to the shaft N, or by having its front end bifurcated and seated on such shaft astride the wheel N and extending to the rear of the machine. A compensating-pulley, S, is seated on the lever It at such point as to bear on the upper side of the chain 0, between the pulley P and wheel N. A weight, T, is placed on the free end of the lever B, by thelatter passing through a hole in such weight, and the pulleys is caused to bear upon the chain 0 with any desired degree of force by moving the weight T in or out on such lever, such weight being held adjustably in place by means of a setscrew therein. By means of the lever B, pulley S, and adjustable weight ,1 the chain 0 is held under a uniform degree of tightness in all changed positions of the axle W, caused the dili'erent angles of the disk gangs relative to the seed-hopper M. The inner ends of the gangs B are held forward adjustably by connecting-rods and levers, as ,shown in our United States Letters Patent No. 240,993, granted to us May 3, 1881, in disleharrows,

What we claim as our invention, and desire 0 to seeu re by Letters Patent of the United States, is-

1. The combination of the beam B, provided with clips D, the scraper-bar C, seated loosely in such clips parallel with the beam B, scrapers F, arms E, seated adj ustably on the bar 0, lever G, journaled transversely on the beam B, and having its front end bent upward and its rear end bent downward, and the clip b, attached to the bar 0, and adapted to receive the rear end of the lever G, substantially as shown, and for the purpose described.

2. The combination of the beam A, provided with the block 6, the beams B, plates K, and plate J, substantially as shown, and for the 5 purpose specified.

8. The combination of the sprocket-wheel W, rigidly seated on the axle of the disk-gangs, the sprocket-wheel N, rigidly seated on the stirring-shaft N, the fixed pulley P, seated on 6: the rear of the draft-beam A in line with the wheel N, the chain 0, passed around the wheels W and N, and the pulley P, the lever R, pivoted at its front end to the shaft N, the pulley S, seated on such lever and imposed on the chain 0 between the wheel N and pulley P, and the weight '1, seated adjustably on the lever B in the rear of the pulley S, whereby the degree of pressure of the pulley S can be adjusted as desired, for the purpose herein 7o specified.

In testimony whereof we alfix our signatures in presence of two witnesses.
